ABSTRACT:
An exchanger switch for use with a plurality of batteries that extends the useful life of the batteries. In a generator, a first battery can provide power to an external load while also providing power to recharge a second battery. When the first battery is depleted to a certain voltage level, the exchanger switch is activated and the second battery can begin providing power to the external load. The exchanger switch also directs a portion of the power from the second battery to recharging the first battery. The exchanger switch allows the generator to continue providing power to the external load without interruption. Using the batteries as alternating power sources allows the exchanger switch to increase the useful life of the batteries.
